CABLE-SUPPORTING PULLEY-BRACKET.

Specification of Letters Patent.

Application filed February 23, 1910.

Patented Dec. 6, 1910. Serial No. 545,388.

To all whom it may concern:

Be it known that I, WILLIAM T. BUCK, a citizen of the United States,residing at Vliets, in the county of Marshall and State of Kansas, haveinvented a new and useful Improvement in Cable-Supporting Pulley-Brackets, of which the following is a specification.

This invention relates to certain new and useful improvements in cablesupporting brackets, the object being to provide a pulley bracket whichwill support the operating cable in such a manner that all danger of thesame jumping out of the bracket is prevented and at the same time theconnecting arm of the mail carrier is allowed to pass through the samewithout any danger of it becoming caught.

Another object of my invention is to provide a pulley bracket which isexceedingly simple and cheap in construction and one in which the partsare carried by a cross bar, adapted to be secured to supporting postswhereby the lea dways of the operating cable will be held at equaldistance apart in all places.

A still further object of the invention is to provide a pulley bracketwith guide members so mounted in respect to the bracket that the endlesscable will lead back on to the pulley if the same should be accidentallydisplaced.

Another object of my invention is to provide a pulley bracket withdepending diverging guide fingers which are so arranged over the pulleythat the cable will be prevented from jumping to a certain extent and atthe same time the arm connecting the carrier to the operating cable willbe guided through the bracket in such a manner that all danger of thearm becoming caught in the same is prevented.

With these objects in view, the invention consists in the novel featuresof construc tion, combination and arrangement of parts, hereinafterfully described and pointed out in the claims.

In the drawing forming a part of this specification:Figure 1 is an endelevation of an intermediate post showing my improved pulley bracketsecured in position thereon. Fig. 2 is an enlarged side elevation of myimproved pulley bracket partly broken away. Fig. 8 is averticaltransverse section through the same, and Fig. t is a section taken online H of Fig. 2.

In carrying out my improved invention I employ a frame A formed of twosections, A, A having depending apertured lugs A through which passes abolt B for securing the sections together. The section A of the frame Ais provided with an angled upper end, A", adapted to be secured over theend portion of the cross arm M, secured to the post D by a bolt M asclearly shown in Fig. l, and in this figure I have shown a pair ofpulley brackets carried by the cross arm, one being arranged at each endof the arm in such a manner that the same can be used for supporting theleadways of the cable.

The section A of the frame A terminates in a horizontal extension, Ehaving an aper ture formed therein through which extends a guide rod Fwhich extends upwardly therefrom as clearly shown and may be extendedover the top of the post and connected to the bracket upon the other endof the cross arm as shown in dotted line, but I have found that in mostcases that a guide rod of the length shown is sufficient to catch andguide the cable back on to the pulley when the same jumps. The bracketupon the other end of the cross arm is an exact duplicate of the bracketabove described and the description of one is sufiicient for both.

The side bars of the sections A, A of the frame A are thickened as shownat G, having outwardly and downwardly extending lips H which are spreadapart as fully shown so as to form beveled guiding portions for guidingthe arm of the carrier through the same so as to prevent any danger ofthe arm, becoming caught in the frame, and it will be seen that theselips diverge in such a manner that the arm will pass through the samesmoothly. The sect-ions A, A are aperturedas clearly shown in which ismounted a bolt I, forming a shaft for a pulley J which is mountedthereon between the sections and on which the operating cable is adaptedto travel and it will be seen that the enlargements G and the lips Hextend over the peripheral edges of the pulley in such a manner that thecable will be prevented from jumping off of the same unless 'it moves ina vertical line and at the same time the arm can readily pass betweenthe lips over the pulley. The enlargements G are rounded or beveled asshown so as to guide the cable back on to the pulley in case the sameshould accidentally jump off.

The lower end of the guide rod F is provided with an eye F which issecured over the outer end portion of the bolt I as clearly shown forholding the guide rod in its correct position. F or supporting the crossarm M and to provide guide members for conveying the cable back into thepulley bracket in case the cable should jump toward the post, I providea guide rod or member C which is provided with a central eye C formed bycoiling the same through which a bolt or screw end is adapted to passfor securing the same to the post D and the ends of the guide members Gextend down through openings formed in the angle ends 91 of the sectionsA of the fame A and duough bores formed in the cross bar M and havetheir ends threaded and secured by nuts C as clearly shown.

The guide member C and guide rod F diverge as clearly shown from theupper ends of the section A, if so as to form inclined guide members forguiding the operating cable back into the bracket if the cable should byany means jump out of the same and it will be seen that by thisconstruction the cable is carried back into the pulley by its ownweight.

VJhat 5 claim:

1. A pulley bracket comprising a frame formed of two sections having apulley interposed bet-ween the same, a cross arm for supporting saidbracket and diverging members extending upwardly from the respectivesections of said frame. forming a guide for the cable.

2. A pulley bracket comprising a frame formed of two sections eachsection being provided with outwardly extending lips, a pulley mountedin said frame, under said lips and diverging members extending upwardlyfrom the respective sections of said frame.

3. A pulley bracket comprising a frame carrying a pulley cross arm forsupporting said bracket, diverging guide members connected to saidframe, and oppositely disposed depending diverging lips, carried by theside bars of said frame, extending over said pulley.

4E. The combination with a supporting post carrying a cross arm, ofbrackets carried by the ends of said cross arm, pulleys mounted in saidbrackets, a guide member connected to said post and to said bracket, :1guide rod extending upwardly from each of said pulley brackets, saidguide members diverging forming inclined guide members.

i-"r pulley bracket comprising a frame formed of two sections providedwith apertured lugs, a bolt passing through said lugs, the side bars ofsaid sections being provided with thickened portions, having outwardlyprojecting depending and diverging li-ps, a pulley mounted in said frameunder said lips and thickened portions, an inclined guide memberconnected to the inner section of said frame, and an inclined guide rodconnected to the outer sect-ion of said frame.

6. In a device of the kind described, the combination with a supportingpost, of a cross arm connected to said post and carrying bracket framesat its ends, pulleys mounted in said frames, guide members formed on theside bars of said frames over said pulleys, a guide member having acentral eye secured to said post above said cross arm and having itsends connected to the cross arm at the junction of the brackets, andguide rods carried by the outer section of the brackets.
